Not sure where to start?

Pick the question closest to yours. Each answer links to a full guide, and you can watch any of it happen on the live map:

"How do I follow a flight?" Start with how to track any flight.
"How does the map know where planes are?" Read ADS-B explained.
"Why did my flight vanish?" See why flights disappear.
"What plane is that?" Try identifying aircraft overhead.
"Why is my flight late?" Read why flights get delayed.

Every guide stands on its own. You do not need to start at the top.

When you want to see an idea in action, open the live map and follow along. You can also look up any airport, airline or aircraft type as you read, or check how many planes are flying right now.

Frequently asked questions

How does flight tracking actually work?

Aircraft broadcast their GPS position, altitude and speed several times a second over ADS-B on 1090 MHz. A worldwide network of ground receivers picks those broadcasts up and shares them, which is what draws the aircraft you see on a live map.

Why do flights disappear from tracking maps?

Usually because the aircraft has flown beyond receiver coverage, which happens over oceans, deserts and polar regions. It can also mean the flight has landed, or that the aircraft's broadcasts are filtered at the owner's request.

Is flight tracking legal?

Yes. ADS-B transmissions are unencrypted broadcasts on open radio frequencies, and receiving them is legal in most countries. The data is used for research, air-safety analysis and public interest reporting.

Where should I start if I am new to flight tracking?

Begin with how to track any flight in real time, then read what the numbers on a tracker mean. From there the technology hub explains ADS-B, radar and multilateration in plain English.
